Referring to FIGS. 1, 4 and 6 to 8, an ice-making apparatus with an anti-contamination structure includes a housing 110 having an ice-storage chamber 119 defined therein and a front wall 112 having a front opening 111 partially defined therein; a pivotally-movable door 120 having an elongate top end portion 122, wherein the pivotally-movable door 120 is constructed to pivotally move around the elongate top end portion 122 thereof to open or close the front opening 111, wherein an elongate clearance 128 is defined between the elongate top end portion 122 and the front wall 112; an elongate contaminant-guide plate 140 disposed below the elongate clearance 128, wherein the elongate contaminant-guide plate 140 has opposing first and second side ends 142, and the housing 110 has opposing first and second side walls 115, wherein the opposing first and/or second side ends 142 are disposed at or adjacent to the opposing first and second side walls 115 respectively; and first and/or second contaminant-discharge holes 165 defined in the opposing first and/or second side walls 115 respectively, wherein the elongate contaminant-guide plate 140 is constructed to receive contaminants falling down from the elongate clearance 128 and to guide the contaminants toward the first and/or second contaminant-discharge holes 165, wherein each of the first and/or second contaminant-discharge holes 165 is constructed to discharge the contaminants out of the housing 110.

More specifically, the housing 110 may have the ice-storage chamber 119 defined therein and have the front wall 112 having the front opening 111 partially defined therein.

The housing 110 defines an appearance of the ice-making apparatus 100. In the present disclosure, the front wall 112 defines a front portion of the housing 110. The housing 110 houses a cooling system, a control system, and a water circulation system. Meanwhile, the shape of the housing 110 may vary. In an embodiment, the housing 110 is formed to have the shape of a column having a rectangular cross section.

In addition, the ice-storage chamber 119 in which the ices generated by the cooling system is stored is provided in the housing 110. FIG. 1 shows an exterior view of the housing 110 according to an embodiment of the present disclosure. FIG. 4 illustrates the ice-storage chamber 119.

In the present disclosure, the front opening 111 is formed in the front wall 112. The front opening 111 may have various sizes and shapes. In an embodiment, the front opening 111 is formed to have a width substantially equal to a width of the housing 110. The front opening 111 may be partially vertically defined in the front wall 112.

FIG. 1 shows the front opening 111, which is closed by the pivotally-movable door 120. FIG. 4 shows that the front opening 111 is in an open state. Through the front opening 111, the user of the ice-making apparatus 100 can take out the ices from the ice-storage chamber 119.

On the other hand, the pivotally-movable door 120 is located in the front opening 111 and is provided to be pivotable about the elongate top end portion 122 to open and close the front opening 111.

The pivotally-movable door 120 is controlled to open and close the front opening 111. The elongate top end portion 122 acts a pivotal axis so that the pivotally movable door 120 pivotally moves about the elongate top end portion 122.

The shape of the pivotally-movable door 120 substantially corresponds to the shape of the front opening 111. Accordingly, the opening and closing of the front opening 111 is controlled based on the pivotal state of the pivotally-movable door 120.

The elongate clearance 128 is defined between the elongate top end portion 122 and the front wall 112. The elongate contaminant-guide plate 140 is disposed below the elongate clearance 128. The elongate contaminant-guide plate 140 has opposing first and second side ends 142. The housing 110 has opposing first and second side walls 115. The opposing first and/or second side ends 142 are disposed at or adjacent to the opposing first and second side walls 115 respectively. The elongate contaminant-guide plate 140 is constructed to receive contaminants falling down from the elongate clearance 128 and to guide the contaminants towards opposing first and/or second side walls 115 of the housing 110.

In order that the pivotally-movable door 120 is pivotable about the elongate top end portion 122, in embodiments, the elongate clearance 128 is defined between the elongate top end portion 122 and the front wall 112. In other words, the elongate clearance 128 is inevitable since the pivotally-movable door 120 is pivotally coupled, as a separate component from the housing 110, to the housing 110.

FIG. 1 shows a location of the elongate clearance 128. The elongate clearance 128 is formed above the elongate top end portion 122 of the pivotally-movable door 120. The contaminants outside the housing 110 may be introduced into the housing 110 through the elongate clearance 128.

In addition, when the pivotally-movable door 120 pivotally moves to open the front opening 111, a water droplet condensed on the pivotally-movable door 120 may move along an outer surface of the pivotally-movable door 120 toward the clearance 128.

An unhygienic contaminant may be present on the outer surface of the pivotally-movable door 120. The water droplet present on the outer surface of the pivotally-movable door 120 may move toward the elongate clearance 128 while the contaminant is contained in the droplet. Thereafter, when the droplet falls into the ice-storage chamber 119, the hygiene of the ices therein greatly decreases.

Thus, according to the present disclosure, the elongate contaminant-guide plate 140 is positioned below the elongate clearance 128. The elongate contaminant-guide plate 140 may be coupled to the housing 110 such that the plate 140 is positioned below the elongate clearance 128. This configuration is shown in FIG. 4.

Furthermore, preferably, the elongate contaminant-guide plate 140 may extend in a width direction of the housing 110. The opposing first and/or second side ends 142 of the elongate contaminant-guide plate 140 may be disposed at or adjacent to the opposing first and/or second side walls 115 of the housing 110 respectively.

In order for the elongate contaminant-guide plate 140 to accommodate contaminants falling from above, the elongate contaminant-guide plate 140 may be formed to have an elongate concave shape. The housing 110 may preferably have the opposing first and second side walls 115.

The opposing first and/or second side ends 142 of the elongate contaminant-guide plate 140 may be disposed at or adjacent to the opposing first and/or second side walls 115 of the housing 110 respectively.

Accordingly, contaminated water containing various contaminants falling from the elongate clearance 128 is collected by the elongate contaminant-guide plate 140. Then, the contaminated water may flow along the elongate contaminant-guide plate 140 to the opposing first and/or second side walls 115 of the housing 110.

Referring to FIG. 4, in one embodiment, the opposing first and second side ends 142 of the elongate contaminant-guide plate 140 are disposed to face the opposing first and/or second side walls 115 of the housing 110 respectively. Thus, the contaminated water containing various contaminants falling from the elongate clearance 128 is collected by the elongate contaminant-guide plate 140. Then, the contaminated water may flow along the elongate contaminant-guide plate 140 to the opposing first and second side walls 115 of the housing 110. Thus, the contaminant introduced into the housing 110 through the elongate clearance 128 cannot reach the ice-storage chamber 119.

The first and/or second contaminant-discharge holes 165 may be defined in the opposing first and/or second side walls 115 respectively. Each of the first and/or second contaminant-discharge holes 165 may be constructed to discharge the contaminants out of the housing 110. Each of the first and/or second contaminant-discharge holes 165 may be constructed to receive the contaminants from the elongate contaminant-guide plate 140 and to discharge the contaminants out of the housing 110. In embodiments, each of the first and second contaminant-discharge holes 165 may serve as a discharge channel for discharging the contaminant to the outside of the housing 110. The shape of each of the first and second contaminant-discharge holes 165 may vary. The first and second contaminant-discharge holes 165 may preferably be adjacent to the opposing first and second side ends 142 of the elongate contaminant-guide plate 140, respectively. Thus, the contaminants guided along the elongate contaminant-guide plate 140 may be discharged completely through the first and second contaminant-discharge holes 165 out of the housing 110.

Referring to FIG. 6, a portion of one of the opposing first and second side walls 115 having the first and second contaminant-discharge holes 165 defined therein is shown. The first or second contaminant-discharge holes 165 defined adjacent to the opposing first or second side ends 142 of the elongate contaminant-guide plate 140 respectively allows communication between an interior space in the housing 110 and an exterior space to the housing 110.

In FIGS. 7 to 8, one of the first and second contaminant-discharge holes 165 and corresponding one of the opposing first and second side ends 142 of the elongate contaminant-guide plate 140 are shown. This is merely according to one embodiment of the present disclosure. The present disclosure is not limited to this. The positions of the first and second contaminant-discharge holes 165 and the opposing first and second side ends 142 may vary.

According to the present disclosure, in order to prevent the contaminant from entering the ice-storage chamber 119 through the elongate clearance 128, which is formed between the pivotally-movable door 120 and the housing 110, the elongate contaminant-guide plate 140 may be used to prevent the contaminant flowing through the elongate clearance 128 from falling into the ice-storage chamber 119. In this connection, the elongate contaminant-guide plate 140 may be used to guide the contaminant to the opposing first and/or second side walls 115 of the housing 110, in which the contaminant may be discharged through the first and/or second contaminant-discharge holes 165 through the housing 110.

Thus, according to the present disclosure, the contaminant will be prevented from entering the ice-storage chamber 119 through the elongate clearance 128, which is formed between the pivotally-movable door 120 and the housing 110, thereby to suppress the contamination of the ices in the ice-storage chamber 119. In particular, the contaminated water present on the outer surface of the pivotally-movable door 120 and containing the contaminants therein may be effectively be prevented from entering the ice-storage chamber 119.

In FIG. 1 and FIG. 4, in the ice-making apparatus according to an embodiment of the present disclosure, an upper portion of the front wall 112 may be inclined. The front opening 111 may define at least a portion of the inclined upper portion. The elongate clearance 128 is located above the ice-storage chamber 119.

The front wall 112 of the housing 110 may be provided in various shapes. In an embodiment of the present disclosure, the upper portion of the front wall 112 of the housing 110 is inclined. Referring to FIG. 1, the upper portion of the front wall 112 of the housing 110 is inclined while a lower portion of the front wall 112 of the housing 110 extends vertically.

A portion of the inclined wall corresponds to the front opening 111. Referring to FIGS. 1 and 4, a lower portion of the inclined wall defines the front opening 111. The present disclosure is not limited to this. The configuration of the front wall 112 may vary.

As the front opening 111 is provided as a portion of the inclined wall, the ice-storage chamber 119 is located below the elongate clearance 128. Even when the front opening 111 is oriented in a perpendicular manner to the ground, there is a possibility that the contaminant will enter the ice-storage chamber 119. However, when the elongate clearance 128 is located above the ice-storage chamber 119, the anti-contaminant structure according to the present disclosure is particularly important.

In embodiments, the contaminant introduced through the elongate clearance 128 into the housing 110 will fall down and then directly enter the ice-storage chamber 119, which can greatly reduce the hygiene of the ice-storage chamber 119. Therefore, in an embodiment of the present disclosure, the sanitary level of the ice-making apparatus 100 can be greatly improved by preventing the contaminant falling down through the elongate clearance 128 from entering the ice-storage chamber 119.

FIG. 4 illustrates a structure in which the elongate clearance 128 formed between the pivotally-movable door 120 and the housing 110 is located above the ice-storage chamber 119. In this case, the elongate contaminant-guide plate 140 prevents the contaminant falling through the elongate clearance 128 from reaching the ice-storage chamber 119. Further, the first and second contaminant-discharge holes 165 may be defined in the first and side walls of the housing 110 respectively, thereby to discharge the contaminant out of the housing 110.

Referring to FIG. 5, in the ice-making apparatus with an anti-contamination structure according to an embodiment of the present disclosure, the elongate contaminant-guide plate 140 may extend in a downwardly inclined manner toward the first or second contaminant-discharge holes 165.

The elongate contaminant-guide plate 140 guides the contaminant dropped from the elongate clearance 128 to the opposing first or second side walls 115 of the housing 110. In this regard, in order to facilitate the guide of the contaminant, in an embodiment of the present disclosure, the elongate contaminant-guide plate 140 may extend in a downwardly inclined manner toward the first or second contaminant-discharge holes 165.

The embodiment in which the elongate contaminant-guide plate 140 extends in a downwardly inclined manner toward the first or second contaminant-discharge holes 165 is shown in FIG. 5. More specifically, in FIG. 5, the elongate contaminant-guide plate 140 has a highest point in a longitudinal center thereof and a lowest point at each of the opposing first and second side ends 142.

Accordingly, the contaminant collected by the elongate contaminant-guide plate 140 may be moved toward the opposing first and/or second side ends 142 due to gravity. Thus, in the embodiment of the present disclosure, the discharge of the contaminant may be facilitated.

Referring to FIG. 1 and FIG. 6 to FIG. 8, in the ice-making apparatus with an anti-contamination structure according to an embodiment of the present disclosure, the housing 110 has first and second contaminant-receiving chambers 160. The first and second contaminant-receiving chambers 160 are defined within the opposing first and second side walls 115 respectively. The first and second contaminant-receiving chambers 160 may be configured to receive the contaminants from the elongate contaminant-guide plate 140. The first and second contaminant-receiving chambers 160 may communicate with the first and second contaminant-discharge holes 165 respectively, Thus, the contaminants that have received in the first and second contaminant-receiving chambers 160 may be discharged through the first and second contaminant-discharge holes 165 respectively out of the housing 110.

Specifically, each of the first and second contaminant-receiving chambers 160 defines a space in which the contaminant transferred by the elongate contaminant-guide plate 140 is retained before being discharged through the first and second contaminant-discharge holes 165. If an amount of the contaminant from the elongate contaminant-guide plate 140 exceeds an allowable amount of contaminant to be discharged through the first and second contaminant-discharge holes 165, an excessive contaminant may fall again into the ice-storage chamber 119. In an embodiment of the present disclosure, the first and second contaminant-receiving chambers 160 are provided to prevent the excessive contaminants from entering the ice-storage chamber 119.

Each of the first and second contaminant-receiving chambers 160 need not necessarily define a closed space. In one embodiment, each of the first and second contaminant-receiving chambers 160 has a step, a shoulder, or a blocking structure constructed to prevent movement of the contaminants toward the ice-storage chamber 119. Thus, the contaminants received in each of the first and second contaminant-receiving chambers 160 may not fall into the ice-storage chamber 119.

Furthermore, the first and second contaminant-receiving chambers 160 are defined within the opposing first and second side walls 115 of the housing 110 respectively. Preferably, the first and second contaminant-receiving chambers 160 are positioned immediately below the opposing first and second side ends 142 of the elongate contaminant-guide plate 140 respectively. Thus, the contaminants guided along the elongate contaminant-guide plate 140 flows into each of the first and second contaminant-receiving chambers 160.

The first and second contaminant-discharge holes 165 allow fluid-communications between the first and second contaminant-receiving chambers 160 and an exterior space to the housing 110 respectively. Accordingly, the contaminants present in each of the first and second contaminant-receiving chambers 160 may be safely discharged through each of the first and second contaminant-discharge holes 165 out of the housing 110.

In FIG. 1, the first and second contaminant-receiving chambers 160 and the first and second contaminant-discharge holes 165 are not shown. FIG. 6 is an enlarged view of a portion “A” in FIG. 1. FIG. 6 shows a state in which first or second pivotal axial protrusions 117 as will be described below is partially removed from the portion A. In FIG. 6, a position and shape of the first or second contaminant-receiving chambers 160 and the corresponding first or second contaminant-discharge holes 165 are partially shown.

Referring to FIG. 6, in an embodiment of the present disclosure, each of the first and second contaminant-receiving chambers 160 faces each of the opposing first and second side ends 142 of the elongate contaminant-guide plate 140. Each of the first and second contaminant-receiving chambers 160 receives the contaminant from the elongate contaminant-guide plate 140. Then, each of the first and second contaminant-receiving chambers 160 delivers the contaminants to each of the first and second contaminant-discharge holes 165.

A position and shape of each of the first and second contaminant-discharge holes 165 relative to each of the first and second contaminant-receiving chambers 160 may vary. In one embodiment, each of the first and second contaminant-discharge holes 165 is disposed immediately below each of the first and second contaminant-receiving chambers 160 so that all contaminants within each of the first and second contaminant-receiving chambers 160 are discharged through each of the first and second contaminant-discharge holes 165.

An example of a position and shape of each of the first and second contaminant-receiving chambers 160 and each of the first and second contaminant-discharge holes 165 is shown in FIG. 6. FIG. 7 shows a cut portion taken along a line B-B of the ice-making apparatus 100 shown in FIG. 6. Particularly, FIG. 7 shows each of the first and second contaminant-receiving chambers 160 as viewed from an inside of the housing 110.

Referring to FIG. 7, according to an embodiment of the present disclosure, the opposing first and second side ends 142 of the elongate contaminant-guide plate 140 are each close to opposing first and second side walls 115 of the housing 110.

The opposing first and second side ends 142 of the elongate contaminant-guide plate 140 extend downwardly into the first and second contaminant-receiving chambers 160, respectively. Immediately below a bottom of each of the first and second contaminant-receiving chambers 160, each of the first and second contaminant-discharge holes 165 is defined. Each of the first and second contaminant-discharge holes 165 may be communicated with each of the first and second contaminant-receiving chambers 160 and may be structurally partially defined across the bottom of each of the first and second contaminant-receiving chambers 160.

FIG. 8 is a cut portion taken along a line C-C of the ice-making apparatus 100 shown in FIG. 6. Particularly, each of the first and second contaminant-receiving chambers 160 is shown as viewed from a front of the ice-making apparatus 100.

FIG. 8 illustrates a shape of each of the first and second contaminant-discharge holes 165.

According to an embodiment of the present disclosure, each of the first and second contaminant-discharge holes 165 are defined within an outermost edge portion of each of the opposing first and second side walls 115 of the housing 110. Each of the first and second contaminant-discharge holes 165 is not visible in FIG. 1 showing the appearance of the housing 110.

In FIG. 8, shapes of and a relative positional relationship between each of the first and second contaminant-receiving chambers 160, each of the opposing first and second side ends 142 of the elongate contaminant-guide plate 140, and each of the first and second contaminant-discharge holes 165 are shown in accordance with one embodiment.

In an embodiment of the present disclosure, by defining the first and/or second contaminant-receiving chambers 160 in the opposing first and/or second side walls 115 of the housing 110 respectively, a portion of the contaminants guided along the elongate contaminant-guide plate 140 may be efficiently prevented from entering the ice-storage chamber 119. Further, by discharging the contaminants within the first and/or second contaminant-receiving chambers 160 through the first and/or second contaminant-discharge holes 165 respectively, the contaminants may be effectively discharged even in an event of a rapid increase of the contaminants.

Referring FIG. 6 to FIG. 8, in the ice-making apparatus with the anti-contamination structure according to one embodiment of the present disclosure, the first and second pivotal axial protrusions 117 may extend inwardly from inner faces of the opposing first and second side walls 115 respectively. The first and second pivotal axial protrusions 117 may be inserted into first and second pivotal axial grooves respectively defined in both opposing side end portions of the elongate top end portion 122 of the pivotally-movable door 120. The first and second contaminant-receiving chambers 160 may be adjacent to the first and second pivotal axial protrusions 117 respectively.

More specifically, the first and second pivotal axial protrusions 117 may extend inwardly from inner faces of the opposing first and second side walls 115 respectively so as to be rotatably inserted into first and second pivotal axial grooves respectively defined in both opposing side end portions of the elongate top end portion 122 of the pivotally-movable door 120. Thus, the first and second pivotal axial protrusions 117 may act as a pivotal axis for the pivotally-movable door 120.

Alternatively, the first and second pivotal axial protrusions 117 may extend outwardly from the both opposing side end portions of the elongate top end portion 122 of the pivotally-movable door 120. The opposing first and second side walls 115 may have first and second pivotal axial grooves respectively defined therein. Thus, the first and second pivotal axial protrusions 117 may be respectively rotatably inserted into the first and second pivotal axial grooves.

In an embodiment of the present disclosure, each of the first and second pivotal axial protrusions 117 are projected out of the housing 110 such that a pivotal axis of the pivotally-movable door 120 is positioned out of the front opening 111. This ensures that the pivotal movement of the pivotally-movable door 120 is not interfered by the housing 110.

In an embodiment of the present disclosure, the first and/or second contaminant-receiving chambers 160 may be defined within the opposing first and/or second side walls 115 of the housing 110 respectively while the first and/or second contaminant-receiving chambers 160 may level-correspond to the first and/or second pivotal axial protrusions 117 respectively. Thus, the first and/or second pivotal axial protrusions 117 may have a lower level than the elongate clearance 128. The elongate clearance 128 may be defined between the elongate top end portion 122 of the pivotally-movable door 120 and the housing 110. In this connection, the elongate top end portion 122 may be disposed below the elongate clearance 128.

Alternatively, the first and second contaminant-receiving chambers 160 may be at least partially defined in the first and second pivotal axial protrusions 117 respectively. Thus, a space size of each of the first and second contaminant-receiving chambers 160 may further increase.

Furthermore, since each of the first and second pivotal axial protrusions 117 has a lower level than the elongate clearance 128, each of the first and second contaminant-receiving chambers 160 may be easily defined relative to the elongate contaminant-guide plate 140. Referring to FIG. 6 to FIG. 8, it is shown that the first and second contaminant-receiving chambers 160 may be at least partially defined in the first and second pivotal axial protrusions 117 respectively.

Referring to FIG. 6 to FIG. 8, as for the ice-making apparatus with the anti-contamination structure, the elongate contaminant-guide plate 140 may have the opposing first and second side ends 142 which extend downwardly into the first and second contaminant-receiving chambers 160 respectively. This may facilitate the guide of the contaminants into each of the first and second contaminant-receiving chambers 160.

More specifically, the opposing first and second side ends 142 of the elongate contaminant-guide plate 140 are adjacent to the opposing first and second side walls 115 of the housing 110 respectively. The opposing first and second side ends 142 of the elongate contaminant-guide plate 140 may be inserted into the first and second contaminant-receiving chambers 160 defined in the opposing first and second side walls 115 of the housing 110 respectively.

Accordingly, the contaminant moved along the elongate contaminant-guide plate 140 directly moves into the first and/or second contaminant-receiving chambers 160. In embodiments, between the elongate contaminant-guide plate 140 and the first and/or second contaminant-receiving chambers 160, the contaminant does not fall down toward the ice-storage chamber 119. This is due to an absence of a gap between the elongate contaminant-guide plate 140 and the first and/or second contaminant-receiving chambers 160. This leads to an improvement in the hygiene of the ice-storage chamber 119. FIG. 6 to FIG. 8 illustrate the configuration that the opposing first and second side ends 142 of the elongate contaminant-guide plate 140 are inserted into the first and second contaminant-receiving chambers 160 defined in the opposing first and second side walls 115 of the housing 110 respectively.

Referring to FIG. 1, as for the ice-making apparatus with an anti-contamination structure according to an embodiment of the present disclosure, the housing 110 includes first and second contaminant downward channels 182. The first and/or second contaminant downward channels 182 may be defined on outer face portions of the opposing first and second side walls 115 respectively. The first and/or second contaminant downward channels 182 extend downwardly from the first and second contaminant-discharge holes 165 respectively. The first and/or second contaminant downward channels 182 communicate with the first and second contaminant-discharge holes 165 respectively. Accordingly, the contaminants discharged from the first and second contaminant-discharge holes 165 may move downward along the first and/or second contaminant downward channels 182 respectively.

Specifically, the first and second contaminant downward channels 182 are defined in the outer face portions of the opposing first and second side walls 115 of the housing 110 respectively. Each of the first and/or second contaminant downward channels 182 may be implemented as an elongate groove. Upper ends of the first and/or second contaminant downward channels 182 may communicate with the first and second contaminant-discharge holes 165 respectively. Thus, the contaminants discharged from the first and second contaminant-discharge holes 165 may be moved downwards along the first and/or second contaminant downward channels 182 respectively.

Particularly, when the contaminated water residing in the pivotally-movable door 120 and containing the contaminants is discharged through the first and second contaminant-discharge holes 165, the contaminated water flows downwardly along the first and second contaminant downward channels 182. In this embodiment of the present disclosure, this can facilitate management of the contaminated water discharged outside the housing 110.

FIG. 1 shows the appearance of the housing 110 with the first and/or second contaminant downward channels 182 defined therein. The first and second contaminant-discharge holes 165 are not visible in FIG. 1. It may be appreciated that the first and second contaminant-discharge holes 165 may be disposed at the upper ends of the first and/or second contaminant downward channels 182 respectively. According to one embodiment of the present disclosure as shown in FIG. 1, each of the first and second contaminant downward channels 182 may be configured to allow the contaminants discharged from the first and second contaminant-discharge holes 165 to be guided to a lowest level of the housing 110.

Referring to FIG. 1, as for the ice-making apparatus with an anti-contamination structure according to an embodiment of the present disclosure, the first and second contaminant downward channels 182 may extend from the first and second contaminant-discharge holes 165 respectively downwardly toward the lowest level of the housing. First and/or second contaminant container 185 may be disposed on outer faces of the opposing first and second side walls 115 respectively. The first and/or second contaminant container 185 may be removable from the opposing first and/or second side walls 115 respectively. The first and/or second contaminant container 185 may be in communication with the first and/or second contaminant downward channels 182 respectively. The first and/or second contaminant container 185 may be configured to store therein the contaminants guided along the first and/or second contaminant downward channels 182 respectively.

In this embodiment of the present disclosure, the first and/or second contaminant container 185 may be provided to enhance the management function, including removal of the contaminant. The first and second contaminant downward channels 182 may extend from the first and second contaminant-discharge holes 165 respectively downwardly toward the lowest level of the housing 110. In this connection, each of the first and/or second contaminant downward channels 182 may extend vertically or in an angled manner relative to a horizontal direction.

FIG. 1 shows that the first and second contaminant downward channels 182 extend from the first and second contaminant-discharge holes 165 respectively in a vertical manner. In this connection, an oil container may be disposed at each of lower ends of the first and/or second contaminant downward channels 182. The oil container may be configured to collect the contaminant from the first and/or second contaminant downward channels 182.

FIG. 1 shows that the first and second contaminant downward channels 182 extend from the first and second contaminant-discharge holes 165 respectively in a vertical manner. However, the present disclosure is not limited thereto. In this connection, the oil container may be disposed at each of the lower ends of the first and/or second contaminant downward channels 182. The oil container may be configured to collect the contaminant from the first and/or second contaminant downward channels 182. The oil container may be inserted into each of the opposing first and second side walls 115 or may be formed to protrude outwardly from each of the opposing first and second side walls 115.

In one embodiment, the oil container may be removable from each of the opposing first and second side walls 115. The contaminants stored in the oil container are eventually removed. In this embodiment of the present disclosure, the oil container is provided to be detachable or removable from each of the opposing first and second side walls 115 to improve the convenience of removal of the contaminants. Coupling between the oil container and each of the opposing first and second side walls 115 may be accomplished in a variety of ways. In one example, the oil container may be hook-coupled to each of the opposing first and second side walls 115. In another example, the oil container may be coupled to each of the opposing first and second side walls 115 via a bracket.

Referring to FIG. 2 and FIG. 3, as for the ice-making apparatus with an anti-contamination structure according to an embodiment of the present disclosure, in the outer face portion of each of the opposing first and second side walls 115, a guide channel 192 may be defined, which extends from each of the first and second contaminant-discharge holes 165 and communicates with an ice-making water discharge channel 195. Thus, the contaminants discharged through the first and second contaminant-discharge holes 165 may move along the guide channel 192 and then enter the ice-making water discharge channel 195. The ice-making water discharge channel 195 may refer to a channel used to discharge water used in ice-making.

In one embodiment, instead of or in addition to each of the first and/or second contaminant downward channels 182, the guide channel 192 may be provided. The guide channel 192 may be implemented as a guide pipe.

One end of the guide channel 192 communicates with each of the first and second contaminant-discharge holes 165. The other end of the guide channel 192 communicates with the ice-making water discharge channel 195 of the ice-making apparatus 100.

The ice-making apparatus 100 may generate ices using water. For ice-making, water used therein may be drained periodically and fresh water may be supplied to produce ices. Further, water used for cleaning the inside of the ice-making apparatus 100 may be discharged through the ice-making water discharge channel 195.

Thus, the guide channel 192 communicates with the ice-making water discharge channel 195, which discharges water to the outside of the housing 110 during operation of the ice-making apparatus 100. Thus, as the contaminant is removed through the ice-making water discharge channel 195, this embodiment is particularly advantageous in terms of the management of the ice-making apparatus 100.

The position of the ice-making water discharge channel 195 may vary depending on the type of the ice-making apparatus 100. FIG. 3 shows an embodiment in which the ice-making water discharge channel 195 is provided at a lower position of a rear wall of the housing 110 of the ice-making apparatus 100. However, the present disclosure is not limited to this. FIG. 3 show that the guide channel 192 is connected to the ice-making water discharge channel 195.

In one embodiment, one end of the guide channel 192 communicates with each of the first and second contaminant-discharge holes 165 as shown in FIG. 2, while, as shown in FIG. 3, the other end of the guide channel 192 extends to the ice-making water discharge channel 195. Thus, the contaminants guided along the guide channel 192 is eventually discharged through the ice-making water discharge channel 195 out of the housing 110.
